Impact of Land Use Changes and Dynamic Vegetation Changes on Vascular Flora Diversity in Małków-Bartochów (The Warta River Valley)

Abstract

The paper presents the changes of vascular plant flora in the Małków-Bartochów peatland area (the Warta River valley) which took place over a 40-year period. Vanishing, permanent and new components of the flora are presented with a special focus on valuable (protected by the law, threatened and locally rare) species. Changes in the share of ecological groups are estimated and discussed. Anthropogenic and natural factors, directly or indirectly influencing (in the past and at present) flora composition, are noted and analyzed.
